Title: Power transmission fluid
Filed: 1958-06-13
Abstract: A power transmission fluid comprises a major proportion of a mineral oil and minor proportions of (i) a C18 or higher aliphatic monocarboxylic acid and (ii) a neutralization product of a C8 or higher aliphatic amine with a mono- or dialkyl acid pyrophosphate having at least 8 carbon atoms.  Mineral oils mentioned are high V.I. and low pour-point spray, transformer and S.A.E. 10, 20 and 30 lubricating oils having viscosities from 40 S.U.S./100 DEG  F. to 150 S.U.S./210 DEG  F.  The acid is preferably a C18-30 acid, e.g. stearic, eicosanoic, behenic, cerotic or montanic acid or a mixture thereof.  Many examples are given of C8-18 primary and secondary saturated and unsaturated aliphatic amines.  Polyamines such as N-alkyl alkylene diamenes, e.g. C12-18 alkyl trimethylene diamines may also be used. Pyrophosphates mentioned are mono- and di-octyl, dodecyl, tetradecyl, hexadecyl, and octadecyl pyrophosphates.  The neutralization is exothermic and is generally conducted at 50-100 DEG C., preferably below 80 DEG  C., using 1-5 mols. of amine/mol. phosphate, an excess of phosphate being avoided though the product may contain free amine.  Optional ingredients mentioned are minor proportions, e.g. 0.1 to 10 wt. per cent of sulphonates, e.g. oil-soluble Na, K, Ca and Ba petroleum, tetra-t-butyl-naphthalene, dinonyl naphthalene, diwaxnaphthalene, diwaxbenzene, stearylbenzene, t-octylphenol, and waxphenol sulphonates; antioxidants such as (i) Ca, Ba and Zn alkyl, cycloalkyl and aryl mono- and dithiophosphates, numerous specific examples being given including the barium salts of P2S5-polybutene or terpene reaction products, and (ii) mixtures of alkyl phenols and arylamines such as mixtures of di- and tri-C1-5 alkyl phenols with phenyl alpha or beta naphthylamine; and anti-foam agents such as silicone polymers of 100-1000 cs./25 DEG  C. Exemplary compositions include the following constituents; a refined transformer oil of 56.9 S.U.S./100 DEG  F. or a refined lubricating oil of 48 S.U.S./100 DEG  F.; 0.2 wt per cent of stearic acid or 0.3 wt. per cent of cerotic acid; 0.2 wt. per cent of the neutralization product of 2 or 5 mols. of a mixture of hexadecyl-, octadecyl-, octadecenyl-, and octadecadienyl-amines or of 4 mols. of a mixture of C12-18 trimethylene diamines (from tallow) with 1 mol. of dioctyl pyrophosphate; 5 p.p.m. of dimethyl silicone polymer; and calcium petroleum sulphonate plus zinc dimethyl cyclohexyl dithiophosphate or 2,6-di-t-butyl-4-methyl phenol plus phenyl-alpha-naphthylamine.  The properties of these compositions are compared with similar compositions where the above constituents are replaced or supplemented by other constituents including:-n-octyl and lauryl acid phosphates and di- and tri-octyl phosphates, calcium naphthenate and C14-18 alkyl salicylate, and tricresyl phosphate.

July 1, 1931, No. 19032. [Class 18.] In a powder box of the type comprising a receptacle with an apertured cover-plate and a roller which projects through the aperture, the roller is provided with trunnions, and guides for these trunnions are formed integrally with or secured directly to the base of the receptacle so as to be upstanding therefrom and spaced apart inwardly from the side walls of the receptacle. The roller may be fluted and solid or hollow, or comprise a brush. In an embodiment, Fig. 3, the trunnion guides are constituted by pins 13 formed integrally with the base of the receptacle which is concave ; and leaf springs 17 positioned by twelve further pins 16 press the roller upwards. The cover-plate (not shown) has a dished upper surface and is provided with a depending flange of which the lower end fits into a groove 22 in the base, and the top edge of the side wall 19 of the receptacle is cemented into a recess in an annular ledge on the inside of the depending flange of the cover-plate. To prevent leakage of powder, the long edges of the rectangular aperture in the coverplate are bevelled, so that the roller fits closely ; and to ensure that the cover-plate is positioned correctly, lugs to engage with the corresponding members of the pins 13 are formed on the undersurface of the cover-plate at opposite ends of one of the long sides of the aperture. A domed cap-like lid of decagonal shape fits over the complete receptacle. The box is filled by depressing the roller. In a modification, Fig. 6, the trunnion guides are formed by a U-shape strip 28 of springy material which is screwed to the base. The cover-plate 14 is hinged to the receptacle and the outer lid, which has a mirror on its inner surface, is similarly hinged. According to. the Provisional Specification, the roller may be replaced by a wheel or endless band ; the springs 17 are positioned by eight pins grouped in pairs ; the trunnion guides may be constituted by vertical keyways in the base or cut in the interior of the depending flange on the cover-plate ; the bottom of this depending flange is ten-sided ; co-operating keys and keyways are formed on the base, the flange of the cover-plate, and the lid so that these three parts can be assembled in only one position ; the box is filled through a removable plug in the undersurface of the base ; and the box may be of the drawer-andshell type.
